Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a clamping device for a pipe cutting machine. Background Technology

[0002] In the field of machining, the performance of the clamping device of a pipe cutting machine directly affects the accuracy and efficiency of pipe processing. At present, some pipe cutting machines on the market use a chuck-type clamping device, which clamps the pipe fittings through elastic clamping flaps. With its advantages such as uniform clamping force and adaptability to pipe fittings of different outer diameters, it is widely used in the pipe processing industry.

[0003] In actual use, the elastic clamping devices of traditional pipe cutting machines are prone to wear and deformation due to frequent clamping forces and friction with the pipe fittings. The elastic clamps in existing devices are mostly fixed in one piece or have a complex embedded connection method. Replacement requires disassembling a large number of parts and involves a complicated assembly and debugging process, which is not only time-consuming and labor-intensive, but also increases maintenance costs. Although some designs take disassembly into account, they lack a reasonable quick-release structure, resulting in low efficiency of elastic clamp replacement and seriously affecting the continuous operation capability and production efficiency of the pipe cutting machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of cumbersome and inefficient process of replacing the elastic clamping petals in the pipe cutting machine clamping device. Therefore, we propose a pipe cutting machine clamping device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a pipe cutting machine clamping device, including a base plate, a mounting frame fixed to the top of the base plate, a hydraulic cylinder provided on the top of the mounting frame, a pressure plate fixed to the output end of the hydraulic cylinder through the interior of the mounting frame, an elastic clamping flap provided on the bottom inner side of the mounting frame, a placement groove provided on the bottom inner side of the mounting frame, the elastic clamping flap being embedded in the placement groove, connecting plates fixed on both sides of the elastic clamping flap, two connecting shells fixed on the bottom inner side of the mounting frame, the two connecting shells being located on both sides of the elastic clamping flap, a knob threadedly connected to the side wall of the connecting shell, a limit block fixed to one end of the knob located inside the connecting shell, a horizontal plate sliding inside the connecting shell, the horizontal plate being located on one side of the limit block, an insert plate fixed to the other side of the horizontal plate, and a slot matching the insert plate being provided on the surface of the connecting plate.

[0006] Preferably, springs are fixed at both ends of the inner wall of the connecting shell, and the other end of the spring is fixed to the cross plate.

[0007] Preferably, the limiting block is elliptical in shape.

[0008] Preferably, vertical rods are fixed on both sides inside the connecting shell, and grooves matching the vertical rods are provided at both ends of the horizontal plate.

[0009] Preferably, the surface of the knob has multiple strip grooves, which are distributed circumferentially.

[0010] Preferably, rubber pads are provided on both sides of the top of the elastic clip.

[0011] Preferably, both ends of the pressure plate are fixed with sliders, and both sides inside the mounting bracket are provided with sliding grooves that match the sliders.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, by turning the knob, the limiting block is rotated, causing the limiting block to move away from the side of the horizontal plate. While the horizontal plate is no longer squeezed, it is pushed by the spring's rebound force, causing the insert plate to disengage from the slot, thus releasing the fixing of the connecting plate. Subsequently, the user can easily remove the elastic clip from the mounting bracket for replacement or maintenance. The entire process is simple and convenient, requiring no disassembly of multiple parts, effectively improving the replacement efficiency of the elastic clip, reducing maintenance costs, and ensuring the continuous operation capability and production efficiency of the pipe cutting machine.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0016] Reference Figures 1-4As shown, this utility model provides a technical solution: a clamping device for a pipe cutting machine, including a base plate 1, a mounting frame 2 fixed to the top of the base plate 1, a hydraulic cylinder 3 set on the top of the mounting frame 2, a pressure plate 4 fixed to the output end of the hydraulic cylinder 3 through the interior of the mounting frame 2, an elastic clamping flap 5 set at the bottom of the inner side of the mounting frame 2, a placement groove 6 opened at the bottom of the inner side of the mounting frame 2, the elastic clamping flap 5 embedded in the placement groove 6, connecting plates 7 fixed on both sides of the elastic clamping flap 5, two connecting shells 8 fixed at the bottom of the inner side of the mounting frame 2, the two connecting shells 8 respectively located on both sides of the elastic clamping flap 5, a knob 9 threadedly connected to the side wall of the connecting shell 8, a limit block 10 fixed at one end of the knob 9 inside the connecting shell 8, a horizontal plate 11 sliding inside the connecting shell 8, the horizontal plate 11 located on one side of the limit block 10, an insert plate 12 fixed on the other side of the horizontal plate 11, a slot 13 matching the insert plate 12 opened on the surface of the connecting plate 7, and springs 14 fixed at both ends of the inner wall of the connecting shell 8. The other end of 14 is fixed to the horizontal plate 11. By turning the knob 9, the limiting block 10 is rotated, moving the limiting block 10 away from the side of the horizontal plate 11. While the horizontal plate 11 is not squeezed, it is pushed by the rebound force of the spring 14, causing the insert plate 12 to disengage from the inside of the slot 13, thus releasing the fixing of the connecting plate 7. Then, the user can easily remove the elastic clip 5 from the mounting bracket 2 for replacement or maintenance. After replacement, the elastic clip 5 is embedded in the placement slot 6, and the elastic clip 5 is initially limited by the connecting plate 7. Then, the knob 9 is turned again, causing the limiting block 10 to rotate and squeeze the horizontal plate 11. While the horizontal plate 11 is squeezed, the insert plate 12 is inserted into the inside of the slot 13, fixing the connecting plate 7. The installation of the elastic clip 5 is then completed. The whole process is simple and convenient to operate, without the need to disassemble multiple parts, effectively improving the replacement efficiency of the elastic clip 5, reducing maintenance costs, and ensuring the continuous operation capability and production efficiency of the pipe cutting machine.

[0017] Reference Figure 4 As shown in this embodiment, the limiting block 10 is elliptical in shape. Through the elliptical design of the limiting block 10, a larger contact area can be generated with the horizontal plate 11 during rotation, thereby providing a more stable extrusion force, ensuring that the horizontal plate 11 can move smoothly when it is extruded, avoiding shaking or jamming, and further improving the stability and reliability of the device.

[0018] Reference Figure 4 As shown in this embodiment: vertical rods 15 are fixed on both sides inside the connecting shell 8, and grooves 16 matching the vertical rods 15 are opened at both ends of the horizontal plate 11. Through the structure of the vertical rods 15 and the grooves 16, the movement trajectory of the horizontal plate 11 can be restricted to avoid tilting and affect stability.

[0019] Reference Figure 4As shown in this embodiment: the surface of the knob 9 is provided with multiple strip grooves, which are distributed in a circular pattern. The design of the strip grooves can increase the friction of the operator's hand and prevent slippage.

[0020] Reference Figure 3 As shown in this embodiment: rubber pads 17 are provided on both sides of the top of the elastic clamping flap 5. By setting the rubber pads 17, the friction between the elastic clamping flap 5 and the pipe can be increased when the pipe is clamped, preventing the pipe from sliding or shifting during processing. At the same time, the rubber material has a certain elasticity and buffering effect, which can reduce the clamping force on the pipe to a certain extent, avoid damage to the pipe, and protect the surface quality of the pipe.

[0021] Reference Figure 2 As shown in this embodiment: both ends of the pressure plate 4 are fixed with sliders 18, and both sides inside the mounting bracket 2 are provided with sliding grooves 19 that match the sliders 18. By setting the sliders 18 and the sliding grooves 19, the pressure plate 4 can be limited, avoiding the phenomenon of shaking of the pressure plate 4 during movement, and further improving the stability of the pipe cutting machine clamping device.

[0022] Working principle: The user rotates the limiting block 10 by turning the knob 9, moving the limiting block 10 away from the side of the horizontal plate 11. While the horizontal plate 11 is no longer compressed, it is pushed by the rebound force of the spring 14, causing the insert plate 12 to disengage from the slot 13, thus releasing the fixing of the connecting plate 7. The user can then easily remove the elastic clip 5 from the mounting bracket 2 for replacement or maintenance. After replacement, the elastic clip 5 is embedded in the placement slot 6, and the connecting plate 7 provides initial positioning. Then, the knob 9 is turned again, causing the limiting block 10 to rotate and press against the horizontal plate 11. Simultaneously, the horizontal plate 11 is compressed, causing the insert plate 12 to engage with the slot 13, fixing the connecting plate 7. This completes the installation of the elastic clip 5. The entire process is simple and convenient, requiring no disassembly of multiple parts, effectively improving the replacement efficiency of the elastic clip 5, reducing maintenance costs, and ensuring the continuous operation and production efficiency of the pipe cutting machine. The elliptical design of the limiting block 10 allows for easy movement during rotation. The horizontal plate 11 has a larger contact area, providing a more stable extrusion force and ensuring that it moves smoothly under pressure, avoiding wobbling or jamming. This further improves the stability and reliability of the device. The structure of the vertical rod 15 and the groove 16 restricts the movement trajectory of the horizontal plate 11, preventing tilting and affecting stability. The design of the strip groove increases the friction of the operator's hand, preventing slippage. The rubber pad 17 increases the friction between the elastic clamp 5 and the pipe when clamping it, preventing the pipe from sliding or shifting during processing. At the same time, the rubber material has a certain elasticity and cushioning effect, which can reduce the clamping force on the pipe to a certain extent, preventing damage to the pipe and protecting the surface quality of the pipe. The slider 18 and the groove 19 limit the pressure plate 4, preventing it from wobbling during movement, further improving the stability of the pipe cutting machine clamping device.
